How is it being reinvented? "The desktop has gone from just a beige tower to all these new [designs]: touch, 170+ desktop [all-in-one] focused apps," an Intel spokesman told CNET.

In the GDC release, Intel goes on to cite "tiny PCs," small Steambox gaming systems, and portable AIO (all-in-one) PCs in the kitchen as reinvention.

Probably better, however, to call it a tweak to the desktop PC's internals, at least as far as Intel is concerned. Those modifications include the chipmaker's first 8-core processor for gaming rigs.

"For those who demand the highest processor core count and memory bandwidth on the desktop, Intel will deliver an 8-core, 16-thread Intel Core processor Extreme Edition in the second half of this year," Lisa Graff, an Intel vice president and general manager, said at GDC earlier this week.

Other changes to the desktop that Intel mentioned are: an upcoming 5th generation Broadwell chip -- which will be Intel's first 14-nanometer processor and the first desktop chip to feature its own Iris Pro graphics (currently popular in laptops such as Apple's MacBook Pros) -- and an unlocked Haswell processor for the overclocker crowd.

"Intel is optimistic about the enthusiast segment," said Nathan Brookwood, the principal analyst at Insight 64. "There's not a lot of competition in the high-end segment" so it's a space that Intel can own, he said.

"Intel's desktop business is its No. 2 business at 43 percent of client [processor] shipments and was growing more than other segments for Intel in '13," the spokesman added.
